The goal of a brush program is to reduce or eliminate any undesirable encroaching woody species without damaging the desirable understory growth. The benefits of a proper brush program are:

• Increased sight distance
• Reduced shading prevents ice from forming on road surface
• Better sign visibility
• Reduces the need for mechanically cutting brush which encourages faster and denser regrowth
• More cost-efficient than time-consuming mechanical means
• Increases area of safe recovery zones
• Ability to selectively control low-growing brush
• Proper applications can provide a trimming effect
